I have a love/hate relationship with continuous lighting. On one hand, I see the absolute necessity in bringing it along for every single shoot, especially since I tend to use smaller-sensor cameras that aren't necessarily the best low-light performers. Enter the Scorpion Lights. (That totally sounds like a kung fu movie)
One of the worst situations to be in while on a video shoot is not having enough light. Your footage will either turn out noisy because of a high ISO or worse: underexposed. I recently took a Litepanels MicroPro out on shoot with me because I wasn't sure what kind of lighting conditions I'd be dealing with and boy am I glad I did.
